Description

Technical Field

[0001] The utility model relates to the technical field of bedding, in particular to a double-layer pillow. Background Art

[0002] Pillows are essential bedding in people's daily lives. Since a person spends one-third of his or her life sleeping, incorrect neck pillow spacing and load-bearing capacity will hinder the comfortable posture of the cervical spine, stimulate and cause neck pain. It is particularly important to choose a pillow that assists sleep and adjusts a good sleeping posture.

[0003] Currently, most pillows on the market are single-layer structures, with a small number of double-layer structures. Their height and shape are fixed and cannot meet the needs of different people. During use, users often need to adjust their sleeping position by increasing or decreasing the height of the pillow or stacking multiple pillows. This method is neither convenient nor can it accurately meet the user's personalized needs for pillow height and shape. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a double-layer pillow with a clever design that can easily switch between a wavy pillow and a flat pillow to meet the user's personalized needs for pillow height and shape.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] A double-layer pillow comprises two pillow bodies of identical size, wherein the front side of the pillow bodies has a horizontal height of 50-60 mm, and the rear side of the pillow bodies has a horizontal height of 30-40 mm. The two pillow bodies are divided into an upper pillow and a lower pillow according to their installation positions. When the upper and lower pillows are installed, the sides of the upper and lower pillows with the same horizontal height can be installed on the same side of the pillow body and combined to form a wave pillow. When the upper and lower pillows are installed, the sides of the upper and lower pillows with different horizontal heights can be installed on the same side of the pillow body and combined to form a flat pillow. The pillow body can be switched between a wave pillow and a flat pillow by horizontally rotating the upper and lower pillows 180 degrees.

[0007] Preferably, the contact surface between the upper pillow and the lower pillow is set as a connecting surface, and the connecting surface of the upper pillow is provided with a card slot running through the left and right ends, and the connecting surface of the lower pillow is provided with a connecting block integrally connected to the left and right ends thereof, and the connecting block is snapped into the card slot; wherein, the connecting surface of the upper pillow and the lower pillow is a symmetrical structure on the front and back sides.

[0008] Preferably, a plurality of connecting blocks and card slots are evenly arranged.

[0009] Preferably, the pillow body is provided with an ergonomically designed recessed area on the surface opposite to the contact surface, wherein the recessed area is recessed from the center points of the four sides of the pillow body toward the center of the pillow body.

[0010] Preferably, the structural density of the lower pillow is greater than that of the upper pillow.

[0011] Preferably, the upper pillow and the lower pillow are both made of polyurethane.

[0012] In summary, the advantages of the present invention are as follows:

[0013] The present invention combines two pillows of equal size, but with different front and back heights. Users can change the shape of the pillow by simply rotating the upper or lower pillow 180 degrees. This not only improves the user experience but also offers the following benefits: improved sleep quality, reduced risk of cervical spondylosis, and meeting the pillow needs of different groups of people.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0021] It should also be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0022] The following is a detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings.

[0023] like Figures 1 to 4 As shown, a double-layer pillow includes two pillow bodies 1 of the same size. The front horizontal height of a single pillow body 1 is 50-60 mm, and the back horizontal height of a single pillow body 1 is 30-40 mm. The two pillow bodies 1 are divided into an upper pillow 2 and a lower pillow 3 according to their setting positions.

[0024] Specifically, the double-layer pillow has two combination forms, namely a wave pillow and a flat pillow.

[0025] Wave pillow: When installing the upper and lower pillows 2 and 3, the sides of the two pillows at the same level can be installed on the same side of the pillow body 1 to form a wave pillow. The higher side of the wave pillow is 100mm high, and the lower side is 80mm high.

[0026] Flat pillow: When installing the upper pillow 2 and the lower pillow 3, the sides with different horizontal heights can be installed on the same side of the pillow body 1 to form a flat pillow. The height of both sides of the flat pillow is 90mm.

[0027] By rotating the upper pillow 2 / lower pillow 3 180 degrees horizontally, the pillow body 1 can be switched between a wave pillow and a flat pillow. Users can freely adjust the height combination according to their needs.

[0028] like Figures 1 to 3 As shown, the contact surface between the upper pillow 2 and the lower pillow 3 is a connecting surface 4. The connecting surface 4 of the upper pillow 2 is provided with a slot 5 extending through both ends. The connecting surface 4 of the lower pillow 3 is provided with a connecting block 6 integrally connected to both ends. The upper pillow 2 and the lower pillow 3 are connected together by engaging the connecting block 6 with the slot 5. The connecting surface 4 of the upper pillow 2 and the lower pillow 3 is symmetrical in front and back. This symmetrical structure allows the upper pillow 2 to still engage with the lower pillow 3 after rotation.

[0029] The upper pillow 2 and the lower pillow 3 are both made of polyurethane. Due to its properties (the surface is slightly sticky after foaming), there will be a large friction force on the connecting surface 4, so that when the upper pillow 2 and the lower pillow 3 are connected, the connecting block 6 will not slide on the slot 5, thereby ensuring the structural stability of the double pillow.

[0030] like Figures 1 to 3As shown, in order to further enhance stability, a plurality of connecting blocks 6 and card slots 5 are evenly arranged.

[0031] like Figures 1 to 3 As shown, in order to make the double-layer pillow fit the human body better and increase comfort, an ergonomically designed recessed area 7 is provided on the opposite side of the pillow body 1 to the contact surface. The recessed area 7 of this surface is recessed from the center points of the four sides of the pillow body 1 toward the center of the pillow body 1.

[0032] The structural density of the lower pillow 3 is greater than that of the upper pillow 2. The upper pillow 2 is softer and can better wrap around the cervical spine, while the lower pillow 3 is harder and can support the neck pillow to provide a supporting effect.

[0033] like Figures 1 to 3 As shown, the upper pillow 2 features several massage zones. Independent turbines on either side leverage the tension of the pillow core to achieve scientific, linear decompression, mitigating the formation of sleep-induced wrinkles like lines around the eyes and nasolabial folds. The center area features stacked turbines of varying sizes, wrapping around the back of the head to stabilize and support the head and neck during back sleep, ensuring consistent support for the spine.

[0034] The above is a description of the embodiments of the present invention. Through the above description of the disclosed embodiments, professional and technical personnel in the field can implement or use the present invention. Various modifications to these embodiments will be obvious to professional and technical personnel in the field. The general principles defined in this article can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features disclosed herein.
